Durch Elektronenbeugung konnten die Karbide M,3Cg6 und Mg;C sowie die Karbonitride MX 
und M,X nachgewiesen werden. Weiterhin traten die intermetallischen Phasen y”-NbNiz, 
(Mo, Nb)Niz und n-Niz Ti auf. Von diesen Phasen waren M,3Ce und y*_NbNiz nicht stabil. 
The Precipitation and Recrystallization Behaviour of the 
Nickel-Base Alloy Inconel 625 
The precipitation behaviour of the nickel-base alloy Inconel 625 was investigated light and 
electron microscopically in the temperature region between 600 and 1100° C for times 
between 5 min and 3000 hrs, and a time-temperature-precipitation diagram was determined. 
Furthermore the recrystallization behaviour was determined at temperatures between 800 
and 1250° C and deformations up to 35 %. 
The carbides M,3Cg and Mg6C as well as the carbonitrides MX and M, X could be found by 
electron diffraction. Furthermore the intermetallic phases y*_NbNiz ‚ (Mo,‚Nb)Niz and 
n-Niz Ti were found. Of these phases M,3Cg and y*-NbNiz are not stable.
